Abstract:
A method of masking wind turbine noise from a wind turbine. Masking noise is generated to produce resultant noise with a modulation depth which is less than a modulation depth of the wind turbine noise and an average level which is greater than an average level of the wind turbine noise. The masking noise is either un-modulated masking noise with a substantially constant level, or amplitude-modulated masking noise which is phase-shifted relative to the wind turbine noise and has a modulation depth which is less than the modulation depth of the wind turbine noise.
